I agree with Al, like usual, on this one. A 555 timer will work just fine.

First link on Google seemed to look pretty good: http://www.dprg.org/tutorials/2005-11a/index.html

Try it out. This is a cheap and reliable solution. Probably way more reliable and safer than using a microcontroller.

Still the biggest reliability and safety problem will be the speed controller. Just with the Jaguar's reputation for failing out of the blue, I would use the trusted Victor 884. Keep it clean and away from any metal shavings and don't backfeed power into it by pushing your scooter around. You may also consider an 883 since it has a little more power handling than the 884, seeing that you're just running a simple scooter.
